menu_post(3X) menu_post(3X)
NAMEmenu_post - write or erase menus from associated subwin-
dows
SYNOPSIS#include<menu.h>
int post_menu(MENU *menu);
int unpost_menu(MENU *menu);
DESCRIPTION
The function post_menu displays a menu to its associated
subwindow. To trigger physical display of the subwindow,
use refresh or some equivalent curses routine (the
implicit doupdate triggered by an curses input request
will do). post_menu resets the selection status of all
items.
The function unpost_menu erases menu from its associated
subwindow.
RETURNVALUE
These routines return one of the following:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argu-
ment.
E_POSTED
The menu has already been posted.
E_BAD_STATE
Routine was called from an initialization or termina-
tion function.
E_NO_ROOM
Menu is too large for its window. You should consider
to use set_menu_format() to solve the problem.
E_NOT_POSTED
The menu has not been posted.
E_NOT_CONNECTED
No items are connected to the menu.

NOTES
The header file <menu.h> automatically includes the header
file <curses.h>.
PORTABILITY
These routines emulate the System V menu library. They
were not supported on Version 7 or BSD versions.
